IMPROVEMENT 11v PAPER-BOX MACHINES.

Nature and Objects of my IIITGHfiOll.

My inventionconsists in certain novel combinations and arrangements of parts for creasing, embossing,

forming and uniting the blanks from which the envelopes or boxes are made, and for holding them in shape while they are drying; and it has for its-object the production of envelopes, 820., at a less cost than formerly, by facilitating the operation of making them. A caveat, No. 2,560, was filed for this invention on the 27th day of August, 1868.

Description of the Drawing:

Figure l is a side elevationof my improved machine. v v

Figure 2 is a horizontal section through the line A A of fig. 1.

Figure 3 is a vertical longitudinal sectionthrongh the line B B, fig. 2,

Figure 4 is a horizontal section through the line 0 0, fig. 3.

Figure 5 is a vertical transverse section through the line D D, fig. 4.

Figure 6 is adetached sectional view, showing the position of the former a at the time it is commencing to fold the blank.

Figure 7 is a view showing the shape of the blank from which the boxes are made.

General Description.

The main shaft 7) is provided with suitable bearings in the frame a, and has a crank-wheel, c, scoured upon each end, which gives motion to the cross-head 0 through the medium of the connecting-rods (l d.

The cross-head e slides in the vertical. guides ff, secured to the frame of the machine, and rcciprocatcs the former e secured to it. a

The table a is to be provided with the necessary mechanism for feeding the blanks to the fibrmer, and for gumming-the edgesof the flaps; but, as these are employed and embraced in the construction of all machines of this character, the same are not illustrated in the-drawing, and a detailed description is deemed unnecessary.

The plate or table a, has an opening in its center, immediately beneath the former through which the latter descends in forming the blanks.

A folder, 9, is pivotedupon the table at g g, in line with and projecting a little over the opening in the The. Schedule referred to in these Letters Patent and making part of the same.

-H.H 4 IVIAXFIELD, of the city, county,

I table.

It is provided with side wings 7t 71, and is so arranged with relation to thcVfin'mer c that the latter, in its descent, will strike against the inner edge of the folder 9 and turn it up, so that, as the former descends, the side wings It will turn up the end flaps of the blank, and the folder 1 will perform the same office for the side of the blank.

Upon the ascent of the former the folder is drawn back into place -by a spring.

The creasing-knite l, pivoted to the frame gt, performs the otlice of creasing that part of the blankdbrining the flap of the envelope. It is operatedby the cam m, on the main shaft 1), whose shape permits the knife I, at the proper time, to drop upon the blank and crease it by forcing into the groove in the table a.

The parts which communicate motion to the knife from the cam on consist of the lever m and connecting-rod m.

Beneath the table a, and around the opening in it, there are four rollers, k, composed of some material to give them a proper degree of elasticity, and held in bearings, one upon each side of the opcnin They perform the ofliceof creasing and pressing the gummed edges of theblanks together as the former descends" between them.

The drum 12, whose surface is provided wish aserics o! rcceivers, 'r, is arranged upon the main shaft 1), in such relation to the former c that, at each time of its descent, a receiver is in position to take the completed box or envelope from the former, and hold it during the process of drying.

The drum receives an intermittent rotary motion in a reverse direction from the main shaft upon which it is hung, through the medium of the cam 0, on the main shaft, and the levers 1) and q, which operate the pawl q in such manner that, at each revolution of the shaft, the pawl engages with a tooth of the ratchet wheel secured to the side of the drum, andrevolvcs it in the direction of the arrow 2, the distance neccs' sary to bring a receiver into position beneath the former.

The spring n, which engages with the ratchet-wheel, prevents the drum being moved otherwise than in the regular manner by the pawl q, and the spring t performs the ofiice of a discharg'cr, to force the boxes or envelopes out of the receivers.

\Vhen it is desired to emboss or ornament the sides of the boxes or envelopes, the face of the former .is made with the required figure, in relief, upon it, as represented in fig. 5, so that, as the former dcscends, the blank is pressed between the die on the former and the rollers k, and the design quickly embossed or printed upon theblauk whileit is being folded.

The die or figure to be embossed or printed may be also arranged upon the surface of one of the rollers k instead of upon the former in which case it would be necessary to substitute a roller with an unyielding surface; and the former and roller may also be so arranged that either may be changed at pleasure, whenever it is required to substitute another design or figure for the one in use.

The sides of the blank opposite those that the folder turns, are creased and turned up by the pins g; but a second folder, similar to g, may be employed in place of the pins, if preferred, or the folders described and embraced in the Letters Patent No. 7 7 ,502, granted to me May 5, 1868, may be employed instead.

Claims.

I claim as my invention- 1. The combination, with the former e, of the folders g, for folding the flaps upon the former, substantially as described and specified.

2. The combination, with the former, provided with a die, of the embossing-roller 7:, for embossing the boxes as they are formed, substantially as described and specified.

3. The receivers 1, arranged to receive successively the boxes from the former, and hold them until dry, or sufficiently set to retain their form, substantially as described and specified.

Tlle COmbiMtiODWiI-h the receivers 1', of the bar t, or equivalent device, for automatically discharging the boxes from the receivers, substantially as described and specified. Witnesses:
